Overview
SI82F99BCC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver in High-Side/Low-Side configuration with enable (EN) input, supporting SiC and GaN FETs in half-bridge topologies. It delivers 6 kVRMS isolation, <5 ns channel-to-channel skew, 200 kV/μs CMTI, and Selectable Variable Current Drive (SelVCD™) across eight output current levels. Used in onboard chargers and motor drives requiring precise dead-time control and Miller clamping.
For engineers reviewing the SI82F99BCC-IS1R datasheet, SI82F99BCC-IS1R pinout, SI82F99BCC-IS1R application, or SI82F99BCC-IS1R equivalent, this page provides verified functional identity, validated pin mapping for WB SOIC-14, confirmed SelVCD™ current sourcing/sinking behavior, UVLO thresholds (12 V), and automotive-grade AEC-Q100 qualification status - all critical for high-reliability power stage design.
Technical Context
The SI82F99BCC-IS1R implements silicon-dioxide capacitive isolation with differential RF-modulated OOK signaling, enabling robust noise immunity and tight timing matching. Its High-Side/Low-Side architecture uses a single PWM input to drive complementary outputs with programmable dead time via external resistor on DT pin.
It integrates a Miller clamp activated during VO→VOL transitions at VMCTA/B threshold, operates as a precision current source (±10% tolerance over temp/process for 12 V UVLO), and features independent UVLO monitoring per VDDI, VDDA, and VDDB rails - ensuring fail-safe operation during partial power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - meets reinforced insulation requirements per UL 1577, VDE 60747-17, and CSA 62368-1. |
| Channel Skew | <5 ns - enables synchronous switching in high-frequency half-bridges without shoot-through risk. |
| CMTI | >200 kV/μs - prevents false triggering in noisy high-dv/dt environments like SiC/GaN inverters. |
| UVLO Threshold | 12 V on VDDA/VDDB - ensures gate drive remains disabled until sufficient supply voltage is established. |
| SelVCD™ Levels | 8 discrete sourcing/sinking current settings - eliminates external gate resistors and enables dynamic turn-on/turn-off speed tuning. |
| Operating Temp | –40 °C to +125 °C - supports under-hood automotive and industrial ambient conditions. |
| AEC-Q100 Grade | Qualified to Grade 1 - validated for automotive powertrain and charging systems per stress test requirements. |
Pinout & Package
SI82F99BCC-IS1R is housed in a wide-body 14-pin SOIC (WB SOIC-14) package with 8.3 mm creepage and clearance, optimized for reinforced insulation compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input supply | 3–20 V CMOS-compatible rail powering internal digital logic and isolation interface. |
| GNDI | Logic ground reference | Return path for VDDI; galvanically isolated from GNDA/GNDB to maintain barrier integrity. |
| PWM | Single-input control signal | Drives complementary VOA/VOB outputs - high = VOA high / VOB low; low = VOA low / VOB high. |
| EN | Active-high enable | Asserting EN = high enables normal operation; deasserting forces both outputs low unconditionally. |
| DT | Dead time programming | Resistor-to-GND sets dead time (10–110 kΩ → ~10–110 ns); tied to VDDI disables dead time for dual-driver mode. |
| SPD+ | Sourcing current control | Resistor or voltage input selects one of eight turn-on current levels (SPD1–SPD8) for VOA/VOB. |
| SPD− | Sinking current control | Resistor or voltage input selects one of eight turn-off current levels (SPD1–SPD8) for VOA/VOB. |
| VDDA | High-side gate supply | 5–30 V rail powering high-side driver output (VOA); monitored by dedicated UVLO circuit. |
| GNDA | High-side ground | Return for VDDA and VOA; isolated from GNDI to sustain 6 kVRMS barrier. |
| VDDB | Low-side gate supply | 5–30 V rail powering low-side driver output (VOB); independently monitored for UVLO. |
| GNDB | Low-side ground | Return for VDDB and VOB; isolated from GNDI and GNDA. |
| VOA | High-side gate output | Current-source output with integrated Miller clamp; sinks current when VOA falls below VMCTA. |
| VOB | Low-side gate output | Current-source output with integrated Miller clamp; sinks current when VOB falls below VMCTB. |
| SPD− | Sinking current control | Resistor or voltage input selects one of eight turn-off current levels (SPD1–SPD8) for VOA/VOB. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete, matched sourcing/sinking current levels per output - replaces gate resistors and enables adaptive switching speed. |
| Integrated Miller Clamp | Automatically engages during VOA/VOB falling edge below VMCTA/B threshold - suppresses Miller-induced false turn-on without external components. |
| Programmable Dead Time | Resistor-controlled delay (10–110 ns range) between VOA/VOB transitions - prevents shoot-through in half-bridge configurations. |
| High-Voltage Input Tolerance | CMOS inputs withstand up to 20 V with deglitch filtering - compatible with 3.3 V, 5 V, and 15 V controller logic without level shifters. |
| Fail-Safe Output States | No undefined outputs: UVLO, EN=low, DIS=high, or unpowered VDDA/VDDB all force VOA/VOB low - prevents unintended power device activation. |
Applications
| Onboard Charger (OBC) | Industrial Motor Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8239BD-IS1R | Same WB SOIC-14 package and PWM input, but uses DISABLE (DIS) instead of ENABLE (EN); identical SelVCD™, CMTI, and isolation specs. | Requires inverted logic control signal for disable function; suitable where system-level fault signaling is active-low. | Select Si8239BD-IS1R only when controller GPIOs are constrained to active-low disable assertion. |
| UCC5390SCD | TI part with 5.7 kVRMS isolation, 100 kV/μs CMTI, and fixed 4-A peak output - lacks SelVCD™ programmability and Miller clamp integration. | Requires external gate resistors and discrete Miller clamp circuits; not AEC-Q100 qualified. | Choose UCC5390SCD only for cost-sensitive non-automotive designs where dynamic current tuning is unnecessary. |
Compared with SI82F99BCC-IS1R, Si8239BD-IS1R offers identical performance with inverted control logic, while UCC5390SCD trades programmability and integration for lower unit cost - making SI82F99BCC-IS1R optimal for automotive and high-efficiency SiC/GaN systems requiring adaptive gate drive.

FAQ
What is the isolation rating and safety certification status of the SI82F99BCC-IS1R?
The SI82F99BCC-IS1R provides 6 kVRMS isolation for 1 minute and is pending UL 1577 recognition, CSA 62368-1 (reinforced insulation), VDE 60747-17, and CQC GB4943.1 certifications. Its 1500 VRMS working voltage and 10 kV bipolar surge rating meet requirements for reinforced insulation in automotive and industrial power systems. SI82F99BCC-IS1R achieves these ratings through dual silicon-dioxide capacitive barriers fabricated on a single die.
Does the SI82F99BCC-IS1R support both high-side and low-side gate driving in a single package?
Yes, the SI82F99BCC-IS1R is configured as a High-Side/Low-Side driver with a single PWM input controlling complementary VOA (high-side) and VOB (low-side) outputs. It includes dedicated VDDA/GNDA and VDDB/GNDB supplies with independent UVLO monitoring, enabling robust operation even if one side's supply fails. This architecture is optimized for half-bridge topologies in inverters and DC-DC converters.
How does the SelVCD™ technology in the SI82F99BCC-IS1R eliminate the need for external gate resistors?
SelVCD™ makes the SI82F99BCC-IS1R's outputs behave as precision current sources - sourcing and sinking current is set via SPD+ and SPD− pins across eight discrete levels, with ±10% tolerance over temperature and process for its 12 V UVLO variant. Because output current is actively regulated, external gate resistors are unnecessary for speed control or Miller clamping, simplifying layout and improving thermal predictability in SiC/GaN designs.
What is the function of the DT pin on the SI82F99BCC-IS1R, and how is dead time programmed?
The DT pin on the SI82F99BCC-IS1R programs dead time between VOA and VOB transitions using an external resistor (10–110 kΩ) connected to GNDI. Typical dead time follows tDT = 1.73 × RDT + 5.74 ns. Connecting DT to VDDI disables dead time insertion and overlap protection, reconfiguring SI82F99BCC-IS1R as a dual independent driver. A 0.1 µF capacitor placed near DT improves noise immunity.
Is the SI82F99BCC-IS1R qualified for automotive applications, and what does its AEC-Q100 Grade 1 rating mean?
Yes, the SI82F99BCC-IS1R is AEC-Q100 qualified to Grade 1 (–40 °C to +125 °C ambient), meaning it has passed stress tests including HTOL, TC, UHAST, and ESD specific to automotive powertrain and charging systems. This qualification confirms its suitability for under-hood and battery-integrated applications where reliability under thermal cycling, vibration, and voltage transients is mandatory - a key differentiator from commercial-grade alternatives.
